On Sunday, the IAEA verified Iran’s compliance with the terms of the deal in the monthly update report, saying the Islamic Republic has eliminated its most sensitive stockpile of enriched uranium gas under the nuclear accord, Reuters reported.

Talks on striking a permanent and comprehensive deal on the Islamic Republic’s nuclear energy program continued until Friday when Iran and the five permanent members of the UN Security Council – the US, France, Britain, Russia and China – plus Germany agreed on the extension of talks until November 24 with a view to achieving a permanent deal that would end the decade-old dispute over Iran’s nuclear energy program.

Representatives from both Iran and the six countries have said they have reached common ground on many key issues but some serious gaps remain to be bridged.

The two sides sealed an interim deal in Geneva, Switzerland, on November 23, 2013, for a six-month period. The deal, which took effect on January 20, expired on Sunday.

Under the deal, dubbed the Geneva Joint Plan of Action, the six countries undertook to provide Iran with some sanctions relief in exchange for Iran agreeing to limit certain aspects of its nuclear activities.
